Microphone not picking up with my UR28M

Okay so my microphone isn’t picking up with my UR28M in logic pro x.

some friends and I used it once and recorded a song on it, but after that we can’t seem to get the microphone to pick up what so ever :cry: :imp:

I don’t even know where to begin and what the problem would be, any help suggestions or a push in the right direction? do i need to be using cubase?

Is the loopback option on?

what is that? i’m about to look that up and find out
